过去二十几年来,IBM已经为制作1.4nm的微型碳纳米管尝试过几乎每一种可能性了,期望能找到延续硅晶体管通道的方法。时至今日,最小的硅晶体管已经达到原子极限了——例如,4nm硅晶体管通道约由20个原子组成。为了进展到下一个硅晶世代,除了各种缺陷和掺杂不均的问题以外,业界还面临着硅晶体管尺寸进一步缩小的挑战。如果IBM或其他厂商——事实上,中国现正主导碳纳米管的研究——能够实现优化的1.4nm晶体管通道,那么摩尔定律(Moore’slaw)就能再持续向前进展;否则的话,业界就得再发展出一种全新的模式。
Over the past two decades, IBM has tried almost every single possibility of making 1.4-nm microtubes, and hopes to find ways to extend the channels of silicon transistors. To date, the smallest silicon transistors have reached the atomic limit - for example, a 4nm silicon transistor channel consists of about 20 atoms. In order to progress to the next generation of silicon, in addition to a variety of defects and uneven doping problems, the industry is also facing the challenge of further reducing the size of silicon transistors. If IBM or another vendor - indeed, China is now dominating the study of carbon nanotubes - is able to achieve optimized 1.4nm transistor channels, then Moore’s Law can continue to move forward; otherwise, the industry We have to develop a completely new model.
